Debunking 3 Common Myths About CMMC Assessments

Written by MNS Group | Mar 6, 2026 2:53:26 PM

If you're a defense contractor or part of the Defense Industrial Base (DIB), you've likely heard some alarming stories about CMMC certification. Rumors are swirling around cost, timeline, and complexity. These have caused many organizations to panic and procrastinate on their compliance journey.

We're glad to share that many of these fears are based on worst-case scenarios or misunderstandings about how the certification process actually works.

Let's separate fact from fiction and debunk three of the most pervasive CMMC myths.

Myth #1:
"It Costs Over $100,000 to Get an Assessment."

This is perhaps the most intimidating myth, and it's causing many small and mid-sized businesses to question whether pursuing Defense contracts is even worth it.

Truth:

Assessment costs vary dramatically based on the size of your organization, the scope of your environment, and your target CMMC level. For many small to medium businesses pursuing Level 2 certification, assessment costs typically range from $30,000 to $60,000, which is significantly less than the six-figure nightmare many anticipate.

The $100k+ figures you've heard often include:

  • Extensive remediation work for unprepared organizations
  • Consulting fees for companies starting from scratch
  • Costs for organizations with sprawling, complex IT environments
  • Businesses that haven't taken any steps toward NIST 800-171 compliance

Organizations that have already implemented basic security controls, reduced their CUI scope, and prepared documentation properly will find assessment costs far more reasonable. The key is understanding that preparation is the variable you can control.

Caution:

While assessment costs can be overstated, extremely low-cost options should raise caution. In some cases, corners may be cut, or an inexperienced firm may be using your organization to gain experience with the assessment process. The result can be a failed assessment, the added cost of reassessment, or even potential exposure to the False Claims Act.

 

Myth #2:
"It Will Take 6 Months to Get on a C3PAO's Calendar."

Early in the CMMC rollout, there was legitimate concern about a bottleneck. With limited Certified Third-Party Assessment Organizations (C3PAOs) and a wave of contractors needing certification, wait times seemed destined to stretch.

Truth:

There is nuance here. For one, the C3PAO ecosystem is maturing. The Cyber AB has authorized a growing number of assessment organizations, and many C3PAOs are actively seeking clients. Add the hesitation we mentioned above, and the current wait times for scheduling an assessment are often measured in weeks, not months.

That said, don't use this as an excuse to delay. As CMMC requirements become mandatory across more contracts, demand will increase, and the bottleneck may become an issue.

Either way, book as soon as possible to avoid the potential hassles of waiting.

 

Myth #3:
"It Will Take 6 Months to Get Our Business Ready."

For organizations staring at the 110 controls of NIST 800-171, six months of preparation might even sound optimistic. The task seems monumental, especially for businesses without dedicated security teams.

Truth:

Your preparation timeline depends almost entirely on your current state and approach. Some organizations can achieve assessment readiness in 8 to 12 weeks with the right strategy.

The companies facing six-month (or longer) timelines typically:

  • Have CUI scattered across their entire network
  • Require significant infrastructure overhauls
  • Lack any existing security policies or documentation
  • Try to tackle compliance with only internal [likely overburdened] resources

Organizations that streamline their approach, particularly by reducing scope, can compress timelines dramatically.

But don't worry if the above situation applies to your business, there is another way to speed this process up!

Bonus: The Enclave, a Compliance Game-Changer

A CMMC enclave is where strategy becomes your greatest asset. You don't need to secure your entire enterprise; you need to secure the environment where CUI lives.

Enclaves are a dedicated, isolated environment specifically designed to handle Controlled Unclassified Information (CUI). Instead of retrofitting your entire business infrastructure for compliance, you create a secure boundary where all CUI processing occurs.

Enclaves Reduce Cost, Scope, and Timing

Rather than implementing 110 controls across every endpoint, server, and user in your organization, you apply them only within the enclave. Fewer systems in scope means lower implementation costs, reduced licensing fees, and a smaller assessment footprint.

This separation simplifies documentation, clarifies responsibilities, and makes assessor reviews straightforward. What might have taken six months can be accomplished in weeks!

In Summary

CMMC certification doesn't have to be the overwhelming, budget-breaking ordeal that many fear. With the right approach, your path to compliance can be faster, less expensive, and simpler.
